TWA Flight 800


East Moriches became known internationally on July 17, 1996, when TWA Flight 800 exploded 8 miles (13 km) off the coast and fell into the Atlantic Ocean. The U.S. Coast Guard Station, East Moriches, was used by emergency responders, and was the site where the bodies were initially prepared for transport. A helipad was constructed at the station, and the media located their equipment and crews there for breaking news. Today there are parks in Smith Point and Center Moriches on Long Island dedicated to those who died in the crash, and a plaque bearing their names. The cause of the explosion, which killed all 230 passengers and crew on board, was determined to be a short circuit which caused the contents of the centre-wing fuel tank to explode; however, many alternative theories exist.
